Before you update

If you use your device's Personal Hotspot for your computer's Internet connection, update your device wirelessly or connect your computer to another network.

Update your device wirelessly

The easiest way to update your device is wirelessly, also called “over the air.” Here’s how:

Plug in your device to a power source.

Tap Settings > General > Software Update.

Tap Download and Install. Updates might download automatically while your device is connected to Wi-Fi and a power source.

Tap Install, or tap Later to install the update later. If you use a passcode, you'll need to enter it before installing the update.

If you have some free space, but not enough to update over the air, you can either update using iTunes ordelete content manually from your device. Whether you use iTunes or update over the air, you'll have the same amount of free space on your device after you update.
